Frequently Asked Questions

Q: What is the difference between carbon steel and stainless steel concrete screws?

Carbon steel offers higher strength grades (up to 12.9) for structural loads, while stainless steel (A2/A4) provides superior corrosion resistance for outdoor or chemical environments.

Q: Which surface treatment is best for outdoor construction?

For outdoor use, we recommend Hot Dip Galvanized, BZP, or YZP coatings, as they provide a thicker protective layer against moisture and salt.

Q: Can you provide customized lengths for specific masonry projects?

Yes, while our standard range is 70-260mm, our factory capabilities allow for full customization of lengths based on your technical drawings.

Q: What international standards do these fasteners meet?

Our products are manufactured to strictly follow ISO, DIN, ANSI, ASME, ASTM, BS, AS, and JIS standards to ensure global compatibility.

Q: What is the MOQ for customized concrete screws?

The minimum order quantity (MOQ) for our standard and customized fasteners is 1000 PCS.

Q: How are the screws packaged for international shipping?

We offer flexible packaging including heavy-duty cartons and pallets to ensure the products arrive in perfect condition regardless of the distance.
